B-LINE P3BHFD3045 – Frequently Asked Questions
1) Will the B-Line P3BHFD3045 plug-in unit fit any busway, or only Pow-R-Way III?
It is built as a plug-in unit for Pow-R-Way III busway and that is the system it plugs into. The unit is P3BHFD3045, a 3-pole 45 amp circuit breaker plug-in with an HFD frame breaker. If your run is a different manufacturer's busway or an earlier Pow-R-Way generation, the plug-in stab and housing interface is not the same, so match the bus run first.
2) What is the interrupting rating on the 45 amp HFD plug-in unit, and is it enough for a high fault-current service?
Interrupting capacity is 100 kAIC at 240 Vac, 100 kAIC at 480 Vac, and 25 kAIC at 600 Vac. On a 480 volt distribution run that 100 kAIC figure covers most commercial and industrial service fault levels without a series-rated combination. Note the drop to 25 kAIC at 600 Vac, so on a 600 volt system check your available fault current against that lower number.
3) How much space do I need to hang a Pow-R-Way III 45A breaker plug-in, and how heavy is it?
Plan for a unit measuring 21.2 by 12.36 by 5.43 inches and weighing 25 lb. That weight matters on a ladder: a 25 lb plug-in hung overhead onto a bus run is a two-person lift in most shops, and you want the clearance in front of the door for the handle throw before you pick the tap location.
4) What does the HFD frame designation mean on this 45 amp busway plug-in?
HFD is the molded case breaker frame inside the unit, catalogued here under frame type F. The frame sets the physical breaker size and the available interrupting range, while the 45A trip sets the actual overcurrent protection. So you are buying an F-frame breaker trimmed at 45 amps, not a 45 amp frame, which is why the interrupting numbers are far higher than the trip rating.
5) Is this busway plug-in a 3-phase unit, and what load can it feed at 45 amps?
Three poles, 45 amps, so it taps all three phases off the bus run for a 3-phase load. Typical use is a single motor, a rooftop unit, a panel feed, or a machine drop off an overhead bus run in a plant or warehouse. For single-phase or a neutral-required load you want a different pole configuration.
6) Does the B-Line Pow-R-Way III 45A plug-in meet NEMA standards for a spec job?
The unit is NEMA compliant and IEEE certified. For a submittal package on an institutional or industrial job, those are the two standards carried on the P3BHFD3045, along with the 100 kAIC at 480 Vac interrupting rating that usually drives the review.
7) What exact part number do I order for the 3-pole 45 amp HFD Pow-R-Way III plug-in?
Order B-Line P3BHFD3045. One configuration only: 3-pole, 45 amp, HFD frame, 50 percent integral housing ground. There are no finish or option variants to specify, so the part number alone fully defines what ships.
